"Now we're going to be figuring out where KlearGear's assets are and how we can collect them," they said.

Customer service

The row stretches back to December 2008 when John Palmer ordered two items, worth less than $20, as a gift for his wife.

The items did not arrive and after repeated calls to the company the couple were told that the items had never been paid for and had been cancelled.

In response Mrs Palmer posted a review claiming "there is absolutely no way to get in touch with a physical human being" and describing KlearGear's "horrible customer service practices".

Three years later, Mr Palmer received an email demanding that the review be deleted within 72 hours or a fine of $3,500 would be levied as he was in violation of the firm's "non-disparagement clause".

Although the Palmers never sent the money, KlearGear attempted to get it via a debt collection service, which the couple allege damaged their credit rating.

Commonsense victory?

Ars Technica, which has been following the case in detail, said that Descoteaux Boutiques, KlearGear's Paris-based parent firm had contacted it.

Emails from Vic Mathieu director of corporate communications claimed that Mr Palmer had been "belligerent towards our customer care staff and threatened to defame KlearGear if he did not receive free merchandise".

Partner at law firm Harbottle and Lewis, Andy Millmore said that it was a partial victory for common sense.

"I should be able to say something fair and reasonable about a firm I have bought goods from," he said.

"It shouldn't have taken three or four years at massive legal cost to reach that conclusion."
